Bank of Japan to Test Blockchain-Based Reserve Settlement System

The Bank of Japan is taking a pioneering step among G7 central banks by testing blockchain infrastructure for reserve settlement. Governor Kazuo Ueda announced the initiative at the FIN/SUM conference in Tokyo, framing it as a critical adaptation to a rapidly evolving financial ecosystem.

The MOVE signals institutional validation of distributed ledger technology at the highest levels of monetary policy. As global central banks scramble to keep pace with private-sector innovation, Japan's sandbox will focus on tokenizing interbank reserves and securities settlement. The BOJ's participation in the BIS-led Project Agora further underscores its commitment to cross-border wholesale solutions.

Technical risks remain a primary concern. Ueda explicitly identified smart contract vulnerabilities as potential threats to financial stability, suggesting rigorous testing will precede any production deployment. This cautious approach reflects central banking's delicate balance between innovation and systemic safeguards.
